Describe Bessemerization process with neat labeled diagram
After smelting the molten matte is then transferred to a Bessemer converter which is a pear shaped furnace made up of steel and internally lined with lime or magnesia. It is mounted on trunnions and can be tilted in any position. Furnace is provided with pipes known as twyers through which sand and hot air is blown into it. Following chemical reactions takes place in the Bessemer converter.
The molten metal obtained from the Bessemer converter is then poured into sand moulds and allowed to cool. On cooling dissolved SO2 escapes out causing blisters on the surface of copper hence it is called as blister copper. It is 96 to 98% pure
